Example Embodiment

[0024] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] As shown in the accompanying drawings, the construction method of the integrated indoor air exhaust duct structure for waterproofing, unloading, and preventing cross-smoke of the present invention includes the following steps:

[0026] The first step is to prepare the connecting pipe hoop 2. The connecting pipe hoop is made of flame-retardant soft PVC material, which has the function of waterproof and flame-retardant.

[0027] The connecting pipe hoop 2 includes a socket 2-1, a rectangular outer edge is arranged around the bottom wall of the socket 2-1 along the horizontal direction, and the top wall of the socket 2-2 is fixed on the rectangular outer edge. The socket 2-1 and the socket 2-2 are arranged on the same central axis, the inner wall size of the socket 2-2 is larger than the outer wall size of the flue, and the outer wall size ...

Abstract

The invention discloses a construction method of a waterproof, unloading and smoke mixing prevention integrated indoor exhaust duct structure, which comprises the following steps of: 1, preparing a connecting pipe hoop which is made of a flame-retardant soft PVC (Polyvinyl Chloride) material; secondly, a bell mouth of each connecting pipe hoop is hooped and sleeved on an upper opening of one flue located below the connecting pipe hoop, and a lower opening of one flue located above the connecting pipe hoop is inserted into an inserting opening of each connecting pipe hoop; the fixing steel bars on each connecting pipe hoop are fixedly connected with reserved stressed steel bars at the positions of floor slabs of all floors and a floor structural slab of a first kitchen or toilet, and non-shrinkage anti-seepage concrete is poured in reserved flue openings outside all the flues. By the adoption of the method, the flue is prevented from generating accumulated loads, and it is guaranteed that the lower-layer flue is not pressed and damaged due to weight transfer of the upper-layer flue.

Description

technical field [0001] The invention relates to an installation method of an exhaust duct, in particular to an installation method of a prefabricated exhaust duct for an indoor kitchen and toilet. Background technique [0002] Residential kitchens and bathrooms are vertical finished pipe products for removing smoke or exhaust gas, also known as exhaust ducts, ventilation ducts, and flues. Construction requirements are very strict. The common construction method is to carry out flue construction on the reserved flue openings between floors. Due to the difference in construction level of the reserved openings, there is no flue support device on the building structure layer, so that the flue is piled up layer by layer during the construction process. Most of the duct materials are thin-walled cement products, which are easily damaged during the construction process. The weight of the upper flue is directly transmitted to the lower part, resulting in poor construction quality. ...
